It's great that you find our stable branches helpful, but keep in mind
those branches do not include Windows-specific fixes.

So I'm not an expert here, but I understand there are three ways you
can build JSC:
(1) -DENABLE_JIT=ON, -DENABLE_C_LOOP=OFF
(2) -DENABLE_JIT=OFF, -DENABLE_C_LOOP=OFF (?)
(3) -DENABLE_JIT=OFF, -DENABLE_C_LOOP=ON
(-DENABLE_JIT=ON and -DENABLE_C_LOOP=ON are incompatible.)
I believe that nowadays the only 32-bit platforms supported by JIT are
Linux, and there only for ARM and MIPS, not x86. So you're almost
certainly going to need to use -DENABLE_JIT=OFF. That eliminates option
You say the cloop seems unstable for you, which is option (3). So
perhaps you should try option (2) if you haven't already. I'm not
actually sure if that works, because I'm not an expert, which is why I
added that (?) to it. But at least it couldn't hurt to try.
Maybe the Windows port maintainers know more about the status of 32-bit
